LAND-ROLLER.

SPECIFICATION forming part of Letters Patent No. 380,283, dated March 27, 1888.

Original application filed June 7, 1886, Serial No. 204,367. Divided and this application filed September 2, 1885. Serial No.

To aZZ whom it may concern.-

Be it known that I, SYLvEsTER F. HART- LEY, a citizen of the United States, residing at Gouverneur, in the county of St. Lawrence and State of New York, have invented certain new and useful Improvements in Land-Rollers, of which the following is a specification, reference being had therein to the accompanying drawings.

Figure 1 is a front elevation of my improved roller. Fig. 2 is an end elevation. Fig. 3 is a partial vertical section on line 00 m, Fig. 2, looking in the direction of the arrow 1. Figs. 4, 4i, i are detached views showing modifications. Fig. 5 is a vertical section on line y Fig. 4, looking in the direction of the arrow 2, Fig. 4. Figs. 6 and 7 show amodiiication of one of the bearing-boxes.

The invention relates to certain novel features of construction and combination, which will he specifically pointed out in the claims.

A A are the front and rear sides of the box.

B is the tongue.

G O are ends of the box, and are extended down below the body of the box to form hangers for the roller-sections. The extreme lower end of each hanger is recessed so as to straddle and fit closely the three flat rightangled sides of a bearing, E E. (see Figs. 2 and 3.) The hanger is also provided with a narrow throat, 5, extending from the bearing upward, say half the length of the hanger. The squared or right-angled part of the bearing is provided upon at least three of its sides with flanges or lips e,which overlap and engage with opposite sides of the hanger.

d is a bolt seated in the lower forked end of the hanger below the bearing, and serves to grip or clamp the hanger upon the opposite vertical faces of the bearing.

As will be readily understood, the throat b performs the double function of facilitating the desired clamping of the hanger to the box and of increasing the elasticity of the hanger, whereby the bearings can conform to the irregular movements of the axle B without serious cramping of the parts.

F is the seat. G H H are drum-sections, of which the section G may, when desired, be keyed to the {No model.)

axle; but I prefer that the outer sections should run loosely on the axle, in order to facilitate turning the roller in various directions, as may be required, without necessitating that either of the outer sections, H H, should slide over the ground.

It will be noticed that the central section,G, has a length about equal to that of both the sections H H. The object of this is to prevent undue deflection of the axle, I having found that with the ordinary construction of a roller of this length in two drunrsections, whereby there is a bearing and consequent thrust upon the center of the axle, there is, in actual service, apt to be so serious 2. deflection of the axle as to rapidly cut out the bearings; but this is obviated by using a relatively long drum-section in the center, with two relatively short sections at its ends. This defect is largely overcome by making the roller in three drumsections of equal length; but I prefer to make the middle one the longer. As shown in Figs.

1, 2, 3, each drum-section has a groove near its ends, which may be conveniently rolled in after the ends of the sheet or sheets have been riveted together. These grooves serve the double purpose of stiffening theshell and also of furnishing a support for the outer edges of the felly-sections I I,which may be made of wood or metal, and are mounted on the outer ends of spokes t t, which at their inner ends are seated in hub L. These spokes are threaded at their outer ends, and have nuts whereby the fellysections may be thrust out against the inner wall of the shell.

In order to spread the ends of the felly-sections apart, thus producing an additional tension upon the parts, I employ wedges J, mounted on the outer ends of intermediate spokes, K, with nuts on the spokes to force the go wedges between the adjacent ends of the fellies. (See particularly Figs. 2, 4, 5.) Another advantage of using these wedges is this:

I am enabled to use fellies of such length that when under satisfactory tension their ends are 9 5 so far apart that water will readily pass between them, wherehy the drum-sections are drained.

In Figs. 4; and 5 the grooving of the shell differs somewhat from that shown in Figs. l,

2, and 8, in that it bulges outward, thus forming ribs or beads on the outer surfaces of the drums. This construction has perhaps some advantages over the other, in that the outer edges of the fellies are seated in grooves, in stead of straddling ridges, so that there is no tendency to split the fellies, but rather a tendency to prevent them from being split. Again, it is probably easier to round the outer edges of the fellies than to groove them. In fact, if the grooves in the shell are wide enough, it may not be necessary to even round the outer edges of the fellies.

In Figs. 6 and 7 I have shown a somewhat different form of bearing, in which the tubular part or cylindrical-shaped part M has an upward projecting flange, m, secured to the lower ends of the hangers O by bolts n and nuts.

I do not wish to be limited to the exact construction shown of any of the parts, because many modifications will suggest themselves to those who are familiar with this class of machines without departing from the spirit of my invention.

I am aware that the shells of rollers have been grooved at points about midway between their ends, the grooves bulging outward, and also that such shells have been grooved at points near their ends, the grooved part projecting inward. In the first of these constructions it is impossible to make the fellies enter the grooves or engage with them, while in the second, although the grooves are near the ends of the shells, their projecting inward prevents their being used in such manner as to support the fellies against splitting. On the contrary, the fellies must have their outer edges grooved, and therefore any outward pressure of the telly against the shell would tend to split the felly.

I do not in this case claim any of the devices or combinations of devices which constitute the subject-matter of an earlier concurrent application, Serial No. 204,867, filed by me June 7,1886, of which this is a division.

It will be seen that each of these spokes (shown in Fig. 4:) is telescopic, the inner end of one section sliding freely endwise within the outer end of the other section, which latter, by reason of its being cast upon or otherwise formed rigidly with the hub, is adapted to support and keep in line the sliding section.

IVhat I claim is- 1. In a land-rol1er,the combination, with the axle, of wooden hangers having their lower ends provided with throats whereby the hangers are rendered elastic, substantially as set forth.

2. In a 1and-roller, the combination, with a grooved metal shell, of felly-sections engaging with the grooved shell, substantially as set forth.

3. In a landroller, the combination, with a metal shell having at its ends outward-projecting grooves, of a central hub, spokes projecting from the hubs, and fellies mounted on the spokes and having the outer edges seated in the outward-projecting grooves, substantially as set forth. g

4. In a land-roller, the combination, with a metal shell having outward-projecting grooves near its ends, of a central hub, spokes projecting from the hub, fellies mounted on the spokes and having their outer edges seated in the outward-projecting grooves, and means for thrusting the fellies into the grooves of the shell, substantially as set forth.

5. In a land-roller, the combination, with a metal shell, of a central axle, a series of extensible spokes projecting from the axle and engaging at their outer ends With the fellies, substantially as described.

6. In a land-roller, the combination, with a metal shell, of a central axle, a hub on the axle, a series of telescopic spokes mounted on the hub with their outer ends engaging with the fellies, and means for lengthening the spokes to thrust the fellies against the shell, substantially as set forth.

In testimony whereof I affix my signaturein presence of two witnesses.
